The subject matter of this application'is out of our copending application Serial, No, 647,560, filed February 14, 1946, now Patent mme ber 2,473,293 issued June 14,1949.

This invention relates to a metal windowlsash and frame construction. f I

An'object of the invention residesin the pro; vision of awindow frame and-sashconstruction thatlends itself to. standardization to. such ,an extent that theframe may befused with-various window opening constructions, and so that the. muntin patterns may be arranged or rearranged, by the builder after the. window frames and sashes have been delivered to'th'e job,v

With these and other objects in view, such as will appear as this description progresses, the invention'resides in the combination and arrangement'of parts illustrated in" the drawings, de-

scribed in the specification and recited injthe claims.

In the drawings; whereijn"wje have 'shownjo'ne form of the invention: 1

Figure 1 is a vertical elevation the inside: f a window frame and sashes constructedin accordei;

ance with our invention;

Figure v.zis a fragmentary perspective viii'bi a typical muntin construction;

Figure 3'is'an exploded view showing the manner in which the muntins are secured together at their intersection; 1

Figure 4 isa perspective view ofv the resilient clip used in combination with-the muntins.

Referring to Figure 1, which showsacomplete window including the frame and sash, the header of the frame is indicated by the referencejfniif meral l0, the sill by the reference numera I and the jambs by the reference numeral l2. The side'rails of the upper sash are indicated 'byflthe reference numerals l3 and I4 and the horizontal upper and lower rails by the reference numerals i5 and I6, respectively. The side rails 'of'the lower sash are indicated by the -reference numerals l1 and I8 and the upper and lower rails of the lower sash by the reference numerals l9 and 20 respectively. These sash are of the double hung type and are slidable in the usual channels in the jambs.

We have shown the lower sash as being free of muntins and the upper sash as having cross muntins with three lights over three lights, but it is to be understood that the lower sash may have muntins and the number of lights may be varied.

In order that the muntins may be arranged in different designs by the builder on the job we have provided for various arrangements ofthe mu'ntins in the sash. Forjillustrative purposes we; lllfldescribe the muntin arrangement in connection with the upper sash (see- Figure 1). In

this arrangement a horizontalmuntin- 2| and vertical" muntins 22 and 23 are provided. At their points 'of intersection 24 these muntins are interlocked in themanner-illustrated inFigures 2 and '3 jas will-later be described. Each-of the muntins,'jwh'ere it contacts the rail of the sash, isfprovidedfwith a-lip 25 (seeFigure 2) and at these" points the rails have holes formed therein for lthe reception ofself-threading screws 26.

Thusthe-sash may be given the muntin design illustrated in-Figure 1. However, 'so'that thismuntin design may be changed by the builder on the fjob; additional holes' are formed in the rails of the sash; 1 For instance, thefsa'sh maybe providediwith a hole atthe points- 26. which will permitthe useof onehorizontaland one vertical muntin. Of course additional holes in the rails of thesash may be provided vertically to make'it possibleto use'other muntin patterns.

Where the muntins intersect, as for instance 24.lthemuntinsfare' secured together; This intersection and securing together of the muntinsis accomplished by the following means. For illustrative purposes we will describe the g muntin intersections'shown in Figure 2, and in connection with-this description will refer also 4 tratedfinFigurejSY The web 31 of the muntin 2l is recessed at 32, which recess communicates with are'cess .3 3 in the glazing bead-M. Thus when the;two; muntin s are assembled the flange 35'of the muntin Zlwill lie'within the recess 28 of the w muntin 22 and the webs 29 and-3i of the muntins 2i and22will interlock. "Because of the presencejof the 'recesses 30'. 32 and 33, the glazing bead 36 of the muntin 22 will li'ewithin the recess 33 of the muntin 2|. Thus the muntins will be interlocked at their points of intersection with their faces flush.

To preclude separation of the muntins at their intersections each intersection is provided with a pair of spring clips (see Figure 2), which are designed to forcibly maintain the muntins in their assembled positions. The free ends 31 and 38 of each of these clips are'engaged beneath the lip 39 of the adjacent glazing bead to maintain the clips in position. The free ends 31 and 38 of each of the clips resiliently force the intermediate portion of the clips against the flanges
